Hello, i've installed the Darwin calendar server under linux (suse 9.2) and it is running smoothly. I can log into the main "web page" without any problems with both iExplorer 7 and Mozilla 1.7.3 But when I want to "log in" - needed when going down in the "directories" - the iExplorer cannot authenticate correctly (Mozilla can authenticate without any problem). The same problem arises when I want to connect to the server using the open Connector tool (http://openconnector.org/) in MS-Outlook. The server output looks like this: ------------------------------------------------ 2008-01-28 14:16:18+0100 [-] [caldav-8008] [HTTPChannel,0, xxx] GET / HTTP/1.1 2008-01-28 14:16:22+0100 [-] [caldav-8008] [HTTPChannel,0, xxx] GET /calendars/ HTTP/1.1 2008-01-28 14:16:22+0100 [-] [caldav-8008] [HTTPChannel,0, xxx] GET /calendars/ HTTP/1.1 2008-01-28 14:16:22+0100 [-] [caldav-8008] [HTTPChannel,0, xxx] "Directory service <SudoDirectoryService 'Test Realm': FilePath('/home/lars/temp/CalendarServer/conf/sudoers.plist')> has no GUID; generating service GUID from realm name." 2008-01-28 14:16:22+0100 [-] [caldav-8008] [HTTPChannel,0, xxx] "Directory service <XMLDirectoryService 'Test Realm': FilePath('/home/lars/temp/CalendarServer/conf/accounts-test.xml')> has no GUID; generating service GUID from realm name." 2008-01-28 14:16:22+0100 [-] [caldav-8008] [HTTPChannel,0, xxx] "Authentication failed: Incorrect credentials for <XMLDirectoryRecord[users@86587b41-d080-5df3-8135-41b482cf220e(Test Realm)] admin(admin) 'Super User'>" 2008-01-28 14:16:29+0100 [-] [caldav-8008] [HTTPChannel,0, xxx] GET /calendars/ HTTP/1.1 2008-01-28 14:16:29+0100 [-] [caldav-8008] [HTTPChannel,0, xxx] "Authentication failed: Incorrect credentials for <XMLDirectoryRecord[users@86587b41-d080-5df3-8135-41b482cf220e(Test Realm)] admin(admin) 'Super User'>" ................................................
